Ends&Bends is used to generate spatial objects from raw navigation (ship routes) to be included in CDI records to describe the geometries of the observations:
- Typical navigation log files record more than one location / 10 seconds (ex: GPS outputs),
- Size of these navigation log files are not practical to be managed or visualized using standard GIS software or services (WMS, WFS and GML )
Navigation log files must be subset, but sub setting must:
- Keep the same geographical shape of the vessel route to allow accurate spatial queries
- Reduce significantly the number of geographical locations to preserve response time (e.g. 1000 points for one month of deep sea navigation,1000 points for a week of inshore navigation).
